Firebird SQL 5 on Ubuntu 22.04 LTS, packaged and supported by cloudimg as an Azure Marketplace virtual machine image.
Firebird is a mature open source relational database that traces its lineage back to Borland InterBase. It is ACID compliant, supports the ANSI SQL feature set that most line of business applications rely on (stored procedures, triggers, views, user defined functions, transaction isolation up to snapshot), and runs well on modest hardware. Firebird is written in C++ with no Java or Python runtime dependency, which keeps the attack surface small and the image footprint tiny. The server is shipped in SuperServer mode, the multi threaded profile that is the right default for a single virtual machine.
This image ships Firebird configured with remote access enabled on TCP port 3050, wire encryption enabled by default, a randomly generated SYSDBA password written once on first boot to a root only credentials file, and a `demo.fdb` default database ready for connection. The `isql-fb` command line client and the Firebird utilities (`gbak`, `gfix`, `gsec`) are on the system PATH. Ubuntu 22.04 LTS provides the operating system base with kernel security updates through 2027 and extended support to 2032.
Firebird is released under the IDPL and IPL licences — there is no per core, per seat, or per server runtime licence fee. cloudimg provides commercial 24/7 support with a guaranteed 24 hour response SLA, so you get the operational confidence of a supported product alongside the economics of open source licensing.
